Less than ten months after his first trip there, Apple CEO Tim Cook has made a second trip to China after nearly doubling Apple retail stores in the country. Cook met with the head of the Ministry of Industry and Information Technology, Miao Wei, to discuss the development of China’s information technology industry, global mobile communications and Apple’s own business in China.

Cook last visited China in March and promised “greater investment” in China, the world’s biggest market for computers and mobile phones. Since then, Apple has almost doubled its number of retail stores in China and Honk Kong to eleven. There were six last March.

A spokeswoman for Apple, Carolyn Wu, said there are no more details available about Cook’s meeting with Miao, and she has no information on how long Cook will be in China or who else he plans to meet with while he’s there.

China is one of Apple’s most important markets for both retail and supply. Fifteen percent of Apple’s fiscal revenue in 2012 came from China. Tim Cook became the first Apple CEO to visit the country early last year.
